Second International Workshop on Network Slicing - Network Slicing 2020
Call for Papers (CFP)
With the emergence of 5G, the diversity of applications and network users, including vertical markets and social networks, gives rise to dynamically changing needs in terms of network services and resources. Users have today dynamic behaviors and event-related usages². As devices become network agnostic, users also expect ubiquitous access to services, from any device, via any network at any time. In addition to enhanced Mobile Broadband (eMBB) services, 5G will cover smart cities and vertical markets and its design needs to meet the requirements of massive Machine-Type Communications (mMTC), characterized by a very large density of connected objects, Ultra Reliable Low Latency Communications (URLLC), with stringent requirements in terms of low latency and high availability and reliability.
The adoption of virtualization and softwarization for networks and infrastructures is an opportunity of moving from monolithic network solutions to customized end-to-end network services designed on-demand, and dynamically deployed “on-the-fly". An important objective of network slicing is going beyond simple resource sharing and consumption reduction by providing flexible mechanisms for network service provisioning, supported by new deployment models, while ensuring smooth service continuity and automating the management and orchestration of network services and resources.
Slicing approaches are still at their early stage with regards to operational services. Multiple issues are yet to be addressed for slicing to be concretely adopted. For example, slicing of the Radio Access Network (RAN) rises specific issues as real-time requirements of low-layer network functions make their virtualization challenging and reduce slicing flexibility. Indeed, while core and access network slicing is constrained by existing mechanisms, it can be facilitated by new approaches which are the focus of this workshop.
Solutions such as Slice-as-a-Service, RAN-as-a-Service, and Automated Slice Life Cycle with runtime allocation of virtualized resources and network elements bring a series of challenges in the way network services and slices are designed, deployed, provided and intelligently managed.
There are many open questions that need to be addressed, including:
- What are the abstractions and models needed to ensure that slicing is deployable in networks?
- What are the end-to-end issues that need to be addressed to allow slicing everywhere?
- How to define new radio resource allocation and orchestration mechanisms that support the coexistence of a large number of slices?
- How do the existing technologies in computing, networking, and storage, become elements of a slice, and how are they managed in this context?
- Is it better to adapt existing components to support slicing, or is it better to design new ones?
This workshop on Network Slicing aims at providing an international forum for researchers and practitioners from Academia, Industry, network operators, service providers, equipment vendors and manufacturers to discuss and address the challenges deriving from such evolution in the application, the network and the infrastructure layers.

Prospective authors are invited to submit high-quality original technical papers for presentation at the conference and publication in IFIP Networking 2020 Proceedings.
Technical Papers can be of two types: Full papers, up to 6 pages, or Short papers up to 4 pages, both including tables, figures and references.
Papers submitted should describe original, previously unpublished research results, not currently under review by another conference or journal. All submitted papers will be reviewed.
Papers will appear in the conference proceeding and will be submitted on IEEE Xplore.
Only PDF files will be accepted for the review process and all manuscripts must be electronically submitted on EDAS using this link: http://edas.info/N27117.
